  1. Skynet: "{207}{}{Skynet was conceived and developed in the year 2050. Through the use of alien technology a new thinking computer was perfected. In the year 2081, Skynet became self-aware. In 2120 Skynet was given a new set of instructions and then abandoned by the Makers.}"


  1. The Hachiko Interview With Joel Burgess & Jeff Gardiner: Players who found the UFO also found the remains of the pilot, who looks like the old school Roswell grays for the most part. Are these the same models being used for Mothership Zeta? Will the grays be the only enemies or are there a variety of new aliens to fight side-by-side with the gray pilot witnessed in the retail game?
    Jeff Gardiner: "Yes, we're modeling the same basic enemy after the "Roswell grays." There are other enemies that will be uncovered as well, including alien robotics."
